Brandon Marshall is betting his Porsche that he'll outplay Antonio Brown in 2016

Brandon Marshall had an outstanding season in 2015. He set all sorts of franchise records with the New York Jets, including the most receiving yards (1,502) and receptions (109). He also became the first player in NFL history to have a 1,000-yard receiving season with four different teams.

Yet, for as great of a season as Marshall had, Antonio Brown was even better. The Steelers wideout hauled in 136 passes for 1,834 yards and 10 touchdowns. However, Marshall is confident he'll outperform Brown next season, and he's willing to bet his Porsche on it.

Marshall issued Brown a challenge on Wednesday night via Instagram. If Brown has more yards than Marshall, he'll give him his custom Jets-themed Porsche. If Marshall has more than Brown, he'll acquire No. 84's Rolls Royce -- given that Brown agrees, of course.

Perhaps this has something to do with the big news out of Jets camp on Wednesday. That, of course, was the signing of Ryan Fitzpatrick. Marshall and the veteran quarterback were unstoppable last season, and it's clear he believes they'll be even better in 2016.
